lNCLOSiNG CASE FOR ERASIVE RUBBERS.

SPECIFICATION forming part of Letters Patent No.

556,681, dated March 1'7, 1896.

Application filed November 9 1895. Serial No. 568,407. (No model.)

To all whom it may concern.-

' Be it known that I, JOSEPH E. LANDERS, of New Bedford, county of Bristol, State of Massachusetts, have invented an Improvement in lnclosing Cases for Erasive Rubbers, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

Many persons engaged in business find it desirable to carry alwayswith them an erasive rubber, but such a rubber after having been carried in the pocket for any considerable period of time becomes soiled and coated to such an extent as renders it very undesirable for use.

The object of this invention is to provide a suitable casing for such a rubber whereby the latter may be carried in the pocket without injury or soiling, yet may be conveniently and readily exposed when needed for use.

In the preferred embodiment of my invention I so construct the case that the moving parts shall rotate about a common axis, which axis shall also be substantially coincident with that of a preferably circular or disklike rubber.

In the drawings, Figure 1 in vertical section shows an inclosing case embodying my invention, the rubber, however, being in elevation; Fig. 2, a similar view with the rubber exposed; Fig. 3, an edge view of 1; and Fig. 4:, a vertical section on the dotted line a: to, Fig. 11,.

In the embodiment of my invention sclected for illustration herein and shown in the drawings the inclosing case A comprises a plurality of parts (6 a, shown as two in number, but which may be of any desired number, if desired. The two parts a a are each semicylindrical in shape, one fitted and adapted to telescope within the other, the two parts being preferably connected by a pivot o The smaller part, a, is shown as provided at one end with an outturned lip (0 adapted to engage the hooked end a of a spring-tongue a, formed integrally with the part a. At its end opposite the lip a the part a is provided with another outturned lip a, between which and an inturned lip a on the part a l have interposed a suitable, preferably spiral, spring s.

The rubber 1) (shown as circular in shape) is mounted in suitable manner also upon the pivot a about which it may be rotated to expose one or another portion of its surface.

lVhen not needed for use the rubber is concealed by drawing the part a over into its position Fig. l and locking the same by ongagement of its lip a with the hooked looking-ton gue a", in which condition the case and rubber may be readily carried in the vestpocket without danger of soiling or injuring the rubber in the case.

lVhen needed for use, the locking-tongue a may be moved into its dotted position, Fig. l, by the fingers of the hand holding the case, when the spring .9 will automatically throw the cover or smaller part, a, about its pivot in the direction of arrow, Fig. 1, partially, or it may be entirely, exposing one-half of the rubber, in which condition the latter maybe used for crasive purposes. It will thus be seen that the case is automatically opened at least sufficiently to expose a part of the erasive surface, and is locked in closing position to prevent possible exposure of the rubber when carried in the pocket.

My invention is not limited to the particular embodiment herein shown.

Having described my in vcntion, what I claim as new, and desire to secure byl'ietters Patent, is-

1. The herein-described inclosing case for rubbers and the like, the same consisting of a plurality of rotatably-connected and telescoping members, alocking device for locking the same in closed position, and means to automatically open the said members upon release of said locking device, substantially as described.

The herein-described inclosing case for rubbers and the like, the same consisting of a plurality of rotatably-gonnected and telescoping mcmbers, alocking device for looking the same in closed position, a spring interposed between the said members, and tending constantly to move to open the same, substantially as described.

In testimony whereof I have signed my 10 name to this specification in the presence of two subscribing Witnesses.

JOSEPH E. LANDERS.
